Almost all architectures define init_new_context() as a function,
but on ARM, it's a macro and that causes a compiler warning when
its return code is not used:
drivers/firmware/efi/arm-runtime.c: In function 'efi_virtmap_init':
arch/arm/include/asm/mmu_context.h:88:34: warning: statement with no effect [-Wunused-value]
#define init_new_context(tsk,mm) 0
drivers/firmware/efi/arm-runtime.c:47:2: note: in expansion of macro 'init_new_context'
init_new_context(NULL, &efi_mm);
This changes the definition into an inline function, which gcc does
not warn about.
